Apr 8th 2025, 12:21

Researchers discovered the blood vessels at the back of the eye -- called retinal microvasculature -- can show early signs someone is at risk of developing dementia.

Apr 8th 2025, 12:21

Researchers explored the long-term effects of preschool expansion in Japan in the 1960s, revealing significant reductions in risky behaviors amongst teenagers. By analyzing regional differences in the rollout of the program, the study identified links between early childhood education and lower rates of juvenile violent arrests and teenage pregnancy. The findings suggest that improved noncognitive skills played a key role in mitigating risky behaviors, highlighting the lasting benefits of early-education policies.

Apr 8th 2025, 12:19

Two undergraduate medicine students have led a major study examining how cardioprotective glucose-lowering therapies -- medications that lower blood sugar and reduce the risk of heart disease in people with diabetes -- affect the risk of developing dementia.

Apr 8th 2025, 12:18

Calcium transport into and out of mitochondria -- the powerhouses of cells -- is central to cellular energy production and cell death. To maintain the balance of calcium within these powerhouses, cells rely on a protein known as the mitochondrial sodium-calcium exchanger, or NCLX. Now, in new research, scientists have discovered a novel regulator of NCLX activity, a protein called TMEM65, which helps move calcium out of mitochondria, protecting against harmful calcium overload.

Apr 8th 2025, 12:16

When faced with a potential threat, mice often freeze in place. Moreover, when two animals are together, they typically freeze at the same time, matching each other's periods of immobility. In a new study, researchers found that coordination during fear looks different in males and females.

Apr 8th 2025, 12:14

A new study shows a compound found in certain fruits and vegetables could hold key to treating neurodegenerative diseases.

Apr 8th 2025, 12:13

In the first comprehensive, cell-by-cell analysis of brain tissue from individuals with Tourette syndrome, researchers have pinpointed exactly which cells are perturbed and how they malfunction, revealing how different types of brain cells are affected by the condition. Findings from this groundbreaking study provide unprecedented insights into the interplay of different brain cell types in Tourette syndrome, suggesting new therapeutic directions.

Apr 8th 2025, 12:13

Experimental drug NU-9 -- a small molecule compound approved by the U.S. Food and Drug Administration (FDA) for clinical trials for the treatment of amyotrophic lateral sclerosis (ALS) -- improves neuron health in animal models of Alzheimer's disease, according to a new study.

Apr 7th 2025, 11:42

A new artificial intelligence (AI) tool that can help interpret and assess how well treatments are working for patients with multiple sclerosis (MS) has been developed.

Apr 7th 2025, 11:40

New research shows that the adult brain can generate new neurons that integrate into key motor circuits, findings that may point to a new way to treat neurogenerative disorders.

Apr 7th 2025, 11:39

Scientists find the protein IL-17 that fights infection also acts on the brain, inducing anxiety or sociability. This adds to evidence that immune molecules can influence behavior during illness.

Apr 7th 2025, 00:34

Long-term exposure to high levels of air pollution may harm the brain health of older adults in England, finds a new study.

Apr 3rd 2025, 14:37

Female hormones can suppress pain by making immune cells near the spinal cord produce opioids, a new study has found. This stops pain signals before they get to the brain. The discovery could help with developing new treatments for chronic pain. It may also explain why some painkillers work better for women than men and why postmenopausal women experience more pain.
